I was shocked too. Hell most of the guys I know would have not known him. I am also shocked noone but Skupin recognized Blair. That might just be my age showing though.

More to the point, it shows the contestants' age. Someone who is 24 - which a lot of those contestants are, roughly - was born the year Facts of Life went off the air. Thinking back to when I was in my low 20's, I'm pretty sure I wouldn't have recognized the older versions of anyone from, say, Rat Patrol or Daktari.
